To provide a concrete form which enables repeated use of a wood panel and can achieve labor saving.

In a concrete form assembled by arranging wood panels in vertical and/or horizontal directions and connecting them to each other, a connector (20) is configured by forming large diameter cylindrical reinforcing parts (20B) on both left and right sides and/or both upper and lower sides of a plate-like body, an elastic member (20C) is filled into each of the reinforcing parts (20B), a screw hole (20D) is formed in the reinforcing part (20B) so as to penetrate the elastic member (20C) in a front-back direction with respect to the wood panel even when the connector (20) is superposed on the wood panels, the connector (20) is superposed between adjacent side edges of the wood panels, and wood screws (21) are screw-inserted into the screw holes (20D) of the connector (20) against an elastic force of the elastic member (20C) and screwed into the wood panels to connect adjacent wood panels to each other.
